Copper Giant talks "high-grade" core from Mocoa

Executive Summary

• Copper Giant announced assay results from drill holes MD‑049 and MD‑050 at the Mocoa copper‑molybdenum project, confirming a northern extension of the breccia corridor and defining a third high‑grade porphyry core.
• Hole MD‑050 intersected 316 m grading 0.35 % CuEq (including 145 m @ 0.60 % CuEq), while hole MD‑049 returned 477 m grading 0.37 % CuEq with two high‑grade subzones (200 m @ 0.49 % CuEq and 71 m @ 0.43 % CuEq).
• Both holes remain open at depth and laterally, supporting the view that Mocoa hosts multiple scalable high‑grade zones and justifying continued drilling from new lower‑elevation pads.

Key Details

• Hole MD‑050 (third high‑grade core)
• Total intersected interval: 316 m @ 0.35 % CuEq (0.25 % Cu, 0.02 % Mo).
• High‑grade zone within hole: 145 m @ 0.60 % CuEq (0.39 % Cu, 0.05 % Mo).

• Drilling halted at rig capacity in strong potassic altered porphyry with increasing Cu‑Mo grades.

• Hole MD‑049 (northern breccia corridor extension)

• Total intersected interval: 477 m @ 0.37 % CuEq (0.30 % Cu, 0.02 % Mo).
• Subzone 1: 200 m @ 0.49 % CuEq (0.37 % Cu, 0.03 % Mo).
• Subzone 2: 71 m @ 0.43 % CuEq (0.39 % Cu, 0.01 % Mo).

• Final 76 m of hole: 0.39 % CuEq (0.37 % Cu, 0.005 % Mo).

• Operational Context

• Two drill rigs continue operating as part of a 14,000‑m resource expansion program.
• New lower‑elevation drill pads are being advanced to increase efficiency and accelerate step‑out drilling.

• Both holes were designed to test key geological hypotheses influencing the next stage of Mocoa’s growth (breccia corridor continuity and connection between East Valley and core).

• Geological Observations

• MD‑049 intersected strong sericite‑altered porphyry, low‑grade dacite porphyry, crackle‑breccia transitioning to hydrothermal breccia with chalcopyrite/molybdenite matrix.

• MD‑050 encountered a low‑grade volcanic cover, followed by typical Mocoa‑style pyrite/phyllic alteration and potassic altered early microdiorite porphyry hosting Cu‑Mo mineralization.

• Edwin Naranjo Sierra, VP Exploration, NI 43‑101 Qualified Person, reviewed and approved technical information.

Notable Quotes

• “Hole MD‑049 confirmed our hypothesis that the breccia corridor extends further north… These results demonstrate both the continuity and the upside of Mocoa’s mineralization.” – Edwin Naranjo Sierra, Vice‑President Exploration
• “Mocoa keeps delivering across geology, recoveries and infrastructure advantages… More progress is coming, both from the drill bit and from our ground work.” – Ian Harris, President & CEO

Materiality Assessment: Material – Positive (new high‑grade core and corridor extension materially enhance the resource potential of a flagship project).
